Purpose: To reduce off-season technical losses of transformers located at the regions dominated by summerhouses along the Mediterranean Coast. Theory and Methods: LVEF implementation is based on the concept of connecting close by transformer couples through an LVEF cable, which enables supply of total loads of the transformers by only one transformer during off seasons. It is important to avoid parallel operation of the transformers through the LVEF for safety concerns. Results: An interlocking system is designed for this aim in the study. Voltage drop and technical loss analysis are performed with DIgSILENT PowerFactory™ software in the scope of technical analysis. The most prevailing transformer couples for the LVEF implementation are determined based on a priority criterion. A pilot LVEF implementation is performed satisfactorily Conclusion: The most prevailing factors in the feasibility of the proposed methodology are; (1) digging cost for AGEF; (2) Payment to the municipality for the digging; (3) distance between the AGEF transformer couples; (3) capacity and capacity factor of the transformers.
